   Areas affected...Parts of central Mississippi

   Concerning...Severe potential...Watch unlikely 

   Valid 221006Z - 221200Z

   Probability of Watch Issuance...20 percent

   SUMMARY...A brief tornado and locally damaging gusts remain
   possible.

   DISCUSSION...Preceding a midlevel wave approaching the lower MS
   Valley, convection is evolving within low-level confluence bands in
   central MS -- where a moist air mass (lower 70s dewpoints) is in
   place. The JAN VWP is sampling a gradually strengthening low-level
   jet (around 40 kt at 1 km AGL) and an associated clockwise-curved
   low-level hodograph (around 200 m2/s2 0-1 km SRH). Despite weak
   buoyancy, the rich boundary-layer moisture and enhanced streamwise
   vorticity are contributing to a locally favorable environment for
   transient, low-topped supercell structures. A brief tornado was
   reported at 938 UTC southwest of Jackson, MS, and an additional
   brief tornado and locally damaging gusts will remain possible
   beneath the core of the 30-40-kt LLJ as it translates northward
   across central MS.
